This one has been logging miles (i.e lines) in my good ol' ideas file for a long time, I'm finally taking it down the home stretch.
SPOKEN: You gonna show in those down the start?

As I run final mileage in some sneakers near death
I take a look at those shoes and realize - no sole left
And I've been speeding and rushing so long
That even the shoe strings stink and the colour's gone
But I have never dumped a shoe with meters still in it
Me be paying for a plum pair - never you heard that
Now matter how bad they're holding - and you are scolding
I'll go on until I am reduced to walk
I really hate to trot, but if so it's so
As I go I check myself, my untwist', unbroke' - soul
I've the kind of mind that can have Kenyans run home out-psyched
When they see me ignite' - logging miles in the twilight

'Be barefoot 'for the night, running out these dumpster pair of Nikes
Yes barefoot 'for the night, wearing out these dumpster pair of Nikes
I'm thinking there'll be strife, stumbling in these dumpster pair of Nikes
They're stinking up my stride, rotting like these dumpster pair of Nikes

So here's what I'm thinkin' - they might be stinkin'
They've been doin' more o' miles - than the British have isles
So I've done on some glue on the last seams
But the toe-front's rottened open by the fungus cream
I have long deflated soles, no comfort left behind
Got a chafe on my 'nads and I've salt in my eyes
I'm as long way from home as that Bilbo Baggins
And the sun's going down on my wobbly sagging roll
Rest ain't further than a county away
I'm like a butter to knife, I'm melting away
I'm 23 now, but I've been told I look 84
At ERs I visit to and fro

N-S-A-I-D - they sell to me
For the limbs that hurt - both feet and knees

'Be barefoot 'for the night, running out these dumpster pair of Nikes
Yes barefoot 'for the night, trotting out these dumpster pair of Nikes
I'm thinking there'll be strife, stumbling in these dumpster pair of Nikes
They're stinking up my stride, rotting like these dumpster pair of Nikes

Powerbars with honey - Gatorade devoured
Messing up the tummy - colon's going sour
Run is going runny - my underwear is cookin'
But no more o' that lichen (too much information!)
I've hot spots upon burns - they're upon a bunch o' blisters
I've dropped more wreck from my feet - than Texas from twisters
Now on my toes - the Nikes' peeled
Now on my balls - the ones you know are on my shoe-less heels, fool

Run barefoot all the night, now I've dumped my dumpster pair of Nikes
Run barefoot through the night, like a crazed jurassic troglodite
I knew that there'd be strife, wearing down this dumpster pair of Nikes
I'm somehow still upright, zombie wobbling down the street tonight

N-S-A-I-D - you fetch for me
For the limbs now hurt - both hips and knees
N-S-A-I-D - an' hurry please!
For my limbs all hurt - my feet and knees
